The method further includes building a traffic prediction model by aggregating the traffic demand data, and generating a traffic prediction for a specified trip. Related apparatus, systems, techniques and articles are also described.

TECHNICAL FIELD

The subject matter described herein relates to a trip planner and route update system, and particularly, to a mobile trip planner and live route update system.

BACKGROUND

Road transportation in most mega cities, such as those with more than 5 million popular, faces traffic congestion issues caused by increasing number of vehicles and accidents. Since new road construction can be very expensive and sometimes unfeasible due to geographic, structural, or restraints, municipalities are often limited to the existing road infrastructure, and thus unable to cope with the increasing demand. As a result, drivers around the world are faced with increasing traffic congestion and longer travel time. This produces an enormous waste of natural resources and productivity, and generates additional pollution.

Efficient trip planning is difficult because road transportation is spontaneous, with many unexpected/unpredictable but frequently occurring events such as accidents, oil spills, construction, weather and many other factors, which can all contribute to unexpected/unpredictable traffic delays.

While there are existing systems that attempt to address aspects of traffic issues, those systems often focus on the so-called live traffic report and do not address the core of the problem—the lack of sensible and feasible planning.

For example, IBM provides a traffic prediction tool (http://www.ibm.com/smarterplanet/us/en/transportation_systems/nextsteps/solution/N500945X17585D04.html) that utilizes historical traffic data and real-time traffic input from a city's transport system to predict traffic flows over pre-set durations of 10, 15, 30, 45, and 60 minutes. This tool, however, is provided at the macro level for traffic controllers/operators to anticipate and better manage the flow of traffic to prevent the buildup of congestion (e.g., in pro-active signal setting and ramp metering), and does not provide functionality for the individual drivers (end users).

Existing trip planning devices such as portable automotive GPS systems or mobile devices running trip planning applications like Google Map also suffer from a number of disadvantages. For example, while existing trip planning devices and services can provide a live traffic layer on top of personalized trip planning using various sensor networks or crowd sourcing, they unnecessarily transmit a lot of irrelevant/extraneous data to the users. For example, when a user is traveling from point A to B, he/she is typically only interested in things that are relevant along the route, between the two points. Existing applications will nevertheless stream all traffic data across the entire area along the route. Transmitting more data than necessary reduces both application performance and usability. Furthermore, the so-called “live” information is actually based on data that are approximately 5-10 minutes old, and thus may no longer be accurate since, e.g., traffic can build up or dissipate quickly. Consequently, a route that is generated based on old and potentially inaccurate data (e.g. to avoid a previous congested section) may not be efficient if, e.g., the traffic congestion of a road section had already cleared up. Furthermore, these devices/applications cannot predict future congestions.

SUMMARY

The present subject matter provides a computer-implemented method for trip planning. The method includes: receiving traffic demand data comprising a plurality of planned trips, each of the planned trips comprising an origin location, a destination location, a planned route, a departure time in the future, and an end time; building a traffic prediction model by aggregating the traffic demand data; and generating a traffic prediction for a specified trip, the specified trip comprising a specified origin location, a specified destination location, a specified planned route, a specified departure time, and a specified end time, the traffic prediction being generated by checking the specified trip against the traffic prediction model for route overlap between the specified planned route and the planned route of each of the plurality of planned trips, and for travel time overlap between the specified departure and end time, and the departure and end time of each of the plurality of planned trips.

In some variations of the present subject matter, if a further route overlap is found, the method further comprises generating a further route from the specified origin to the specified destination by avoiding route overlap and travel time overlap with the traffic demand data of the traffic prediction model. In some variations, the plurality of planned trips is generated based on a plurality of prior recurring trips.

Similarly, computer systems are also described that may include one or more data processors and a memory coupled to the one or more data processors. The memory may temporarily or permanently store instructions that cause at least one processor to perform one or more of the operations described herein. In addition, methods can be implemented by one or more data processors either within a single computing system or distributed among two or more computing systems.

The subject matter described herein provides many advantages. For example, the present subject matter can provide an easy/intuitive way for drivers of motor vehicles (private or commercial) to plan their trip and notify a central system or a road authority, to collect, e.g., trip start/end status in real time.

DETAILED DESCRIPTION

Roads are in some ways analogous to production lines of a manufacturing factory. For example, both road transportation and manufacturing deal with capacity and demand: while a factory aims to match raw materials/parts with equipment/workforce capacities, transportation needs to match motor vehicles with roads/highways. Additionally, they both have a relatively static capacity: the number of equipment, and workforce do not change drastically on a daily basis just as roads/highways. The real differences include, for example, (1) while the demand of a factory can be carefully collected, planned, and scheduled to match capacity, the demand of road infrastructure by motor vehicles is uncontrolled since, e.g., drivers are typically free to embark on any journey at will; and (2) modeling of road capacity is complicated as many unexpected/unpredictable bottleneck factors can come into play, in addition to more stable parameters such as the length and number of lanes.

By implementing features of the present subject matter, at least some of the limitations of existing technology can be overcome. For example, by collecting data of planned trips including, e.g., the route, start/end time and status, in real time, a better traffic demand/prediction model can be built and trained, and more accurate predictions as well as live traffic conditions can provided for drivers.

FIG. 1 is a diagram illustrating a mobile trip planner and live route update system 100 in accordance with the present subject matter. System 100 includes a plurality of components including: one or more computer/data processors 101, one or more data storages 102, training module 110, planning module 120, prediction module 130, and notification module 140. Each of the modules can be implemented via software (e.g. computer instructions executable by one or more processors), hardware, or any combination thereof. Although these modules are shown to be separate modules, which can be advantageous for ease of updates and modifications, in some variations, one or more of the modules can be combined with one another. For example, the training module 110 and prediction module 130 may be implemented as a single module, while the planning module 120 and the notification module 140 can be implemented as a single module. In some variations, features of the modules can be divided into additional modules.

While details of the features implemented in these modules will be discussed later, as an overview, training module 110 can be configured build and train a traffic prediction model, the planning module 120 can configured to provide planning functionalities, the prediction module 130 can be configured to predict, e.g., one or more traffic characteristics, and the notification module 140 can be configured to transmit, e.g., trip planning data.

FIG. 2 shows a mobile trip planner and live route update architecture 200 of an implementation of the present subject matter. As can be seen, architecture 200 includes one or more mobile devices 201, 202, 203, 204 (fewer or more as desired), which are in data communication with a cloud server 210, which is in turn in data communication with a mobile trip planner and live route update system 220 in accordance with the present subject matter.

Mobile devices 201-204 can each be, e.g., a smartphone, a tablet, a GPS navigation device and the like, and can include one or more components such as: motion sensor(s) including, e.g., gyroscopes, GPS receiver, camera, input device (such as a touch screen), display, as well as one or more data processors and storage configured for processing and transmitting/receiving data.

Cloud server 210 can be, e.g., a web server having an interface or application for communication with the mobile devices and system 220, which can be, e.g., system 100 of FIG. 1. In some variations, system 220 is integrated with cloud server 210, e.g., to communicate directly with the mobile devices. In some variations, additional layers of communication can be added, e.g., between the mobile devices and the cloud server, and/or between the cloud server and the system.

FIG. 3 shows a process flow diagram 300 in accordance with an implementation of the present subject matter for providing, e.g., features of the training module 110 and prediction module 130. At 310, the system receives sensor data from one of the mobile devices. The sensor data can include one or more data such as motion sensor data, gyroscope sensor data, GPS data, date, time, and the like. The system stores the sensor data in a database at 330, and builds and/or trains a traffic model at 340. As more data is received and stored in the database, the traffic model can be trained to better predict traffic patterns. Based on the latest traffic model, the system can generate and/or validate traffic prediction at 350.

FIG. 4 shows a process flow diagram 400 in accordance with an implementation of the present subject matter for providing, e.g., features of the planning module 120 and notification module 140. At 410 and 420, the system receives origin data and destination data, each can be, e.g., location data (the ordering of these steps can be interchanged). At 430, the system receives a departure time (e.g. for a future trip) or a current time (e.g. if the user is ready to embark on the trip). Based on these data, the system generates a route at 440, and transmits the route at 450. In some variations, the route can be generated using, e.g., the traffic model discussed with respect to FIG. 3. In some variations, the system calculates an estimated travel time and/or arrival time, and takes it into account in generating the route. At 480, the system generates traffic demand data, which can be utilized in building/training the traffic model. The traffic demand data can include one or more of: e.g., the generated route, the departure or current time, the estimated travel time, and the arrival time.

At 460 and 470, the system can optionally update the route (e.g. based on the latest traffic model) and transmit the updated route to the mobile devices. At 490, the system receives an end time when the user reaches the destination. Although not shown, the system can generate updated traffic data with the end time for building/training the traffic model.

In some variations, e.g., before the user embarks on the journey, the system can determine one or more route candidates from the origin to the destination. The system can calculate one or more characteristics for each route candidate including, e.g., the travel distance, tolls and the number of traffic lights along the route. The system can also calculate the total journey time of each route candidate and suggest the route based one or more criteria including, e.g., (1) least estimated journey time based on live and predicted traffic updates, (2) least standard deviation of journey time against historical demand fluctuations, and (3) largest number of historical adoptions by the user. In some variations, when there is no significant differences in the predicted journey time (e.g., mean and standard deviation), a further criterion—user preference, can be factored in when determining the suggested route.

In some variations, during the journey, automatic update of route can be provided when, e.g., (1) system receives enough evidence of either demand building up or new bottleneck forming in the road sections coming up based on live demand and traffic reports; and/or (2) a significantly better optional route has been discovered by the system. These and/or one or more alternate routes can be displayed to the user, to enable user-selection. In some variations, one or more threshold factors can be provided, for example, to enable auto update when a new route can reduce the remaining travel time by a factor of, e.g., a threshold percent. In some variations, the updates can be communicated in a safe-driving way such as one or more voice notifications pushed to the mobile device.

It should be noted that by utilizing the traffic demand data, which includes data on planned trips, as well as live data (which eventually becomes historic data), the traffic model and be built/trained to provide more accurate predictions of future traffic conditions.

As shown, the system can receive a pre-planned trip 415, which also includes origin and destination data. In some variations, the pre-planned trip can be a trip that the user intends to take in the future, or a trip that is taken frequently and/or recurring (e.g., to home, to office, to supermarket). The origin may be pre-configured, or may be the user's current location (e.g., manually entered or GPS data from the mobile device).

In some variations, the departure time can be pre-configured (e.g., manually entered), based on a previous time when the trip was taken (e.g., the last time), or an estimated time based on historical data and/or model. In some variations, the end time similarly can also be pre-configured (e.g. manually entered), based on a previous time when the trip was taken (e.g., the last time), or an estimated time based on historical data and/or model.

In some variations, the mobile device can be configured to automatically detect when the user embarks on a trip (e.g. using GPS and/or sensor data). The mobile device can also be configured to transmit data such as time, location, and sensor data automatically during the trip, and/or record the data to be transmitted later. In some variations, the mobile device can also be configured to enter a driving mode when it detects the start of a trip (e.g. through sensors or GPS).

In some variations, the system can be configured to transmit live data received from other mobile devices that are relevant to a user's trip to the user to provide, e.g., live update of traffic conditions.

In some variations, the generated route is determined based on one or more of: live traffic data (e.g. from the traffic model), journey time estimation, per time range and per road section. A road section can be, e.g., a part of a road between two consecutive static bottlenecks such as junctions/traffic lights/ramps/exits. In some variations, automatic update of route can happen when (1) system receives enough evidence of either demand building tip or new bottleneck forming in the road sections coming up based on live demand and traffic reports; and/or (2) a significantly better optional/alternate route in terms of remaining journey time has been discovered by the system. In some variations, the user can select one or more threshold factors, for example, to enable auto update whenever the new route can reduce the remaining journey time by a threshold percentage. In some variations, the update can be communicated in a safe-driving way such as one or more voice notifications pushed to the mobile device. For example, if the system determines there is large demand on the planned road section and planned time period, warning can be generated and displayed on the mobile device to alert the user to opt for a different route.

In some variations, live notifications can be pushed to the mobile devices about the road sections that are ahead or relevant to the trip if the system predicts one or more of, for example, a buildup of traffic congestion, and generates a different route for the user.

References will now be made to FIGS. 5-10, which show various implementations of user interface that can be provided on the mobile device as well as some of the display features. FIG. 5 shows the display of a mobile device. The display includes a mode of transportation 510 (e.g., in the “driving” mode as shown), a planned trip section 520 showing the pre-configured planned trips (e.g., To Home, To Office, To Supermarket, To Workshop, To School, and To Hospital), and trip data 530 showing, e.g., the estimated time. In some variations, for a transportation mode such as private or public, the trip data 530/630 can include the selected route, e.g., shown as stacked and/or colored columns (or bars) with the stacks representing the road sections, the estimated journey time vs. a standard journey time. In some variations, additional information can also be provided for the user.

In some variations, the trip data can be updated by the actual journey detected (e.g. based on GPS data from the mobile device). For example, when heavy traffic is detected, one or more new route options can be generated and pushed to the mobile device as, e.g., voice and/or text notifications.

In some variations, e.g., as shown in FIG. 6, a public transportation mode 610 can be provided with trip information 630, e.g., seating information collected from a central ticketing system (i.e. Translink in Singapore, from which it is possible to know how many people has embarked on which bus/train, remaining seats can be computed by comparing with the bus capacity). The trip information may also include journey data for the current trip (e.g., the journey data of the bus the user is on). In some variations, the system of the present subject matter can determine, e.g., that the user is on a bus, and the bus information from sensor data such as from a GPS sensor of the mobile device. The system can calculate the journey data similar to the driving mode.

In some variations, one or more parameters of trip data can also selected/configured. For example, FIGS. 7-10 show various user-interface and displays that can be provided by the present subject matter where user can browse more details of the selected routes per road section (e.g. at or between different exits of a road) per selected time range (e.g. including the start time and stop time).

In some variations, the system can be implemented using in-memory database technology such as the HANA technology offered by SAP AG. Such implementation can enhance performance by enabling real time analytics to be performed, which is particularly advantageous in providing real time updates and modeling of the present subject matter.
